Share a little about the materials, processes, and techniques used to create this cake I used 2d tip for the pink and 1m tip for purple and buttercream frosting. What are you most proud of? Somebody told me I should start charging for my cakes :-) must mean I'm getting better.?.? What advice would you give someone starting this project? Crumb coat and cool the cake for at least 1/2 hr before you start decorating.
